Abstract
Background: Poly methylmethacrylate (PMMA) is one of the most commonly used denture base material. Various attempts
have been used to strengthen acrylic resin by incorporating filler particles. Method: In the present study zirconium oxide is
used as a filler material and a silane coupling agent is added for bonding with PMMA by two different methods that is sol gel
method and functionalizing zirconium oxide with silane coupling agent. Result: The present study demonstrated a significant
increase in impact strength, surface hardness as the percentage of ZrO2 fillers increased. Conclusion: From the study it
was concluded that incorporation of Zirconium oxide to PMMA will increase in flexural strength, impact strength and
hardness of PMMA and the mechanical property obtained by functionalizing nanoparticles method is better than sol-gel
method.
